Curtis Granderson breaks his arm, is out 10 weeks
The Yankees had been experimenting with moving Granderson to left field with Brett Gardner in center. The injury pushes New York's hand, as Gardner will now move to center and two spare parts, Juan Rivera and Matt Diaz will battle for the everyday left field job. Unless of course the Yankees attempt to make a trade later in Spring Training for a replacement.
Both Rivera and Diaz are major downgrades from Granderson. Rivera, 34, is not a good defender, and he posted just a .285 on-base percentage last season. Diaz, also 34, may be slightly better in the field, but is OBP was just .280 in 2012.
Granderson, who is due to hit free agency after the 2013 season, has been New York's top source of power the last few seasons. In 2012 he hit just .232, but did blast 43 home runs. With Granderson out, the Yankees are now left with Robinson Cano and Travis Hafner (as well as switch hitter Mark Teixeira) as their only real sources of power from the left side of the plate.
Granderson now joins Alex Rodriguez, Derek Jeter (who is expected back in mid-March) and Michael Pineda as key injured Yankees.
